Allright, not heavily modifying, but I need to add a circuit breaker.

My '68 has the original solid state flasher and turn signal switch. It worked beautifully when I first got the truck running, but first I lost my directionals and then I lost my brake lights. Brake light switch has power in and out of it, so that's fine. I pulled the turn signal switch that mounts to the steering column apart and it is fried. The nylon was melted and there were black scorch marks, etc.

I have a replacement switch ordered. When it shows up I want to put a 20 or 30 amp circuit breaker somewhere in the system to prevent this from happening again. I was just thinking I'd splice the breaker into the power wire to the switch (A/460-461).

The question is: will 20-amp be okay or would I need 30? Will splicing into the A/460-461 help keep the flasher from frying in any way or just the switch? If there's one power wire I could put the breaker on to safeguard the system I'd rather just put the one in there.

Anyone know? I need to get this sucker ready for our OD trip and TDS and I'd hate to be using hand signals the whole time.
